APC SMT750RM2UCNC 2U 750VA Rack‑Mount UPS

Overview :

The APC SMT750RM2UCNC is a line‑interactive uninterruptible power supply (UPS) designed to maintain continuity of AC power for critical rack‑mounted IT gear in commercial and distributed IT environments. It’s deployed by network administrators and infrastructure engineers to provide regulated power and backup during utility disruptions for servers, networking equipment, and storage systems.

This UPS delivers 750 VA / 500 W of backup capacity with pure sine wave output and automatic voltage regulation (AVR) to handle brownouts and overvoltage without immediately relying on battery reserves. It includes a set of six NEMA 5‑15R outlets and a NEMA 5‑15P input, suitable for powering multiple devices in a standard 120 V North American power ecosystem.

The unit is designed in a 2U 19‑inch rackmount chassis, fitting into IDF/MDF cabinets, edge data closets, and small data center racks where space is constrained. Rack rails are included for standard installation into 4‑post racks.

Management and monitoring are supported via an Ethernet SmartConnect port with a pre‑installed Network Management Card 2, USB, and RS‑232 interfaces, allowing integration with remote management platforms like EcoStruxure IT or PowerChute Network Shutdown for orchestrated server shutdowns.

A practical deployment example is providing clean, battery‑backed power for a rack containing a 1 U server, a small switch, and associated network interfaces in a branch office closet. In this context, the SMT750RM2UCNC maintains uptime long enough for graceful shutdowns during extended outages or to bridge short interruptions without data loss.

This UPS is not suitable for environments requiring support above 500 W load, UPS clusters for high‑availability data centers, or non‑120 V power domains without appropriate transformers or variants. It also lacks the extended runtime capability of larger modular UPS systems, making it ill‑fitting for long outages without external battery packs.
